Diagramming live failures without drowning the room

Incidents rarely arrive with tidy timelines. We model a “truth ladder” on the board: confirmed facts on the left, hypotheses on the right, discarded ideas crossed with a single line so history stays readable.

Students practise rotating scribes every fifteen minutes so handwriting and shorthand stay legible. The goal is a board auditors could photograph without embarrassment.

When emotions spike, we pause for water and rewrite the customer impact sentence until it fits in two lines. Clarity calms the room faster than reassurance clichés.
